Bellone, a married father of three who is up for re-election next year, insisted he has no idea how his account came to be linked to Knox.

“County Executive Bellone’s Twitter account, which is operated by his staff, has been hacked and an obscene Twitter account was subsequently followed,” said his spokeswoman, Vanessa Baird-Streeter.

“A formal complaint has been filed with Twitter and to the third-party software used to assist in managing the account. His staff has instituted stricter security protocols to ensure an incident like this does not happen in the future.”

The referrals were made after The Post asked his account on Thursday.

The Bellone aide also said that “law-enforcement authorities have been notified and the Suffolk County Police Department is currently investigating.”

There’s no evidence that Bellone exchanged personal messages with the porn star.

The politician best known for blaming a hacker for connecting him to lewd material on the Web was the former Rep. Weiner, who later admitted he was a serial sexter. Weiner resigned from Congress in 2011.

He ran for mayor in 2013, only to crash and burn when new instances of his online dalliances surfaced.

Bellone was one of more than 105,000 fans tracking Belle Knox’s Twitter musings, mostly promoting her porn movies and other sex business.
